I'm in the process of launching a women's fitness apparel brand geared toward the U.S. market and am looking for a reliable partner with experience in high-quality activewear and private label production. Initially, I want to focus on custom women's gym T-shirts but plan to expand the line as the brand grows. I'd love to learn about your capabilities in custom product development, sample creation (including costs), minimum order quantities, available fabrics, and custom branding options. It'd be great to know your production lead times, quality control processes, and shipping arrangements to the U.S. I'm excited about the possibility of a long-term partnership and would like to schedule a video call to discuss how we can work together.
